Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The onpaste property returns the onPaste event handler code on the current element. See the W3C Working Draft at paste.

Syntax

element.onpaste = functionRef;

where functionRef is a function - often a name of a function declared elsewhere or a function expression. See JavaScript Reference:Functions for details.

Example

<!DOCTYPE html>
<html>
<head>
<title>onpaste event example</title>
</head>

<body>
<h1>Play with this editor!</h1>
<textarea id="editor" rows="3" cols="80">
Try pasting text into this area!
</textarea>

<script>
function log(txt) {
  document.getElementById("log").appendChild(document.createTextNode(txt + "\n"));
}
  
function pasteIntercept(evt) {
  log("Pasting!");
}
  
document.getElementById("editor").addEventListener("paste", pasteIntercept, false);
</script>

<h2>Log</h2>
<textarea rows="15" cols="80" id="log" readonly="true"></textarea>
</body>
</html>

This example logs pastes into a textarea.

Notes

This event is sent when the user attempts to paste text.

Since Firefox 13, the preference dom.event.clipboardevents.enabled controls this feature. It defaults to true but can be disabled.

Specification

Not part of specification.

Notes

There is currently no DOM-only way to obtain the text being pasted; you'll have to use an nsIClipboard to get that information.
